I was the first British woman to earn a doctorate...and it happened to be in mathematics in 1885.
I was the first woman in the United States to have a doctorate in mathematics.
My research focus as a mathematics professor at Bryn Mawr College was the development of a catalog of all of characteristics of equations of degree 3 or higher.
I eventually went deaf (and had failing eyesight), which led to my social isolation as a professor...and gave me lots of free time for research.
My most influential paper was a geometric proof of Max Noether's Fundamental Theorem, which previously had been proven only bu algebraic methods.
